Ractopamine

Ractopamine is a phenethanolamine belonging to a class of drugs known as β-Adrenergic agonists (beta agonists) and has been found to increase muscle growth and decrease fat deposition.  Due to the nature of this group of compounds, they have a history of being used illegally, particularly by livestock producers.  Improper use of beta agonists can cause a serious risk to human health due to the residues they leave on the meat and other foodstuffs of animal origin. It is for this reason that in Europe all beta agonists are banned for use in livestock and for improving athletic performance according to EU council directive 96/22/EC.

The Randox Food Diagnostics Ractopamine ELISA test kit offers excellent limits of detection for detection of veterinary drug residues across a range of sample matrices.
